Z SHEETSSHEET 2 STATES JOHN J. BAEUZKY, OF CHICAGO, ILLINOIS.

wmnow on 13003 Loon.

Application filed July 16; 1921. Serial No. 485,247.

To all whom it may concern Be it known that of Chicago, county of Cook, Illinois, have invented ful Improvements Locks, of which the 1, JOHN J. BAHUZKY, a citizen of the United States,

and resident and State of certain new and usein Window 101" Door following is a. specification, and which are illustrated in the accompanying drawings, thereof.

The invention relates to latches'forwirh forming a part dow devices. the principal object of the invention being to providean improved latch adapted to be secured to a window or door for effectively holding the same from move ment in one direction against any force from any position which may be exerted to the end without interfering with movement in the opposite direction, readily adjusted to and but which may be firmly held in an inoperative position to permit free movement of the door or window in either direction. to provide such a latch which A further object of the invention is shall be easily and cheaply manufactured and readily applied for use on any type of door or window.

In the accompanying drawings:

Fig. 1 is a top plan view of the latch showing the same applied to the lower sash of a window, a detail of the upper sash being shown in section and the latch engaging member being in its retracted position;

Fig. 2 is a'sectional view line 2-2 of Fig. 1;

Fig. 3 is a view similar to or inoperative taken on the Fig. 2, but

showing the movable part of the latch in operative position Fig. 4L is a vertical cross section taken on line 4- 1: of Fig. 2;

Fig. 5 is a side elevation of the latch; Fi 6 is a front view of a window showing the latch attached to one of the sashes;

view showing the latch Fig. 7 is a front attached to a swlnging door of ordinary construction Fig. 8 is a front view showing two of the latches applied being and the other at the bottom.

In Figs. 1 to 6 the latch secured to the lower sash to a sliding barn door, one secured thereto at the top of the door 10" is shown as 10 of a Window whose upper sash is represented by the numeral 11. 12 preferably stamped out of of metal and secured to the The latch consists of a housing a single piece sash 10 as by screws 12.

eccentrically 1 1 is located atthe end 15 and serves to move the member 13 into or out of tion.

The opposite end 16 is slotted, as at 26 to enable the rod to be secured in inoperative position by means of a pivoted latch 25, accidental removal of which is prevented by a locking lug 27. In the position shown in Fig. 2, the sash 11 may be raised and lowered at will. As 'shownin Fig. 3 lowering the sash is prevented by the engagement of the sash engaging member 13, owing to its eccentric mounting. Preferably the member 13 comprises a metal block 19 in the form of a sector of a disk having secured within a groove 20, formed'in its curved face, a corrugated strip 21, preferably of indurated composition fabric or hard rubber which tightly grips the sash 11, so as to prevent any slipping of the same. It is desirable to hold the sash engaging member normally in operative position and to accomplish this there is provided a light. spring 22 reacting between a recess 23 in the block 19 and a stud 24 projecting inwardly from the housing 12. When it is desired to raise and lower the upper sash freely, the sash engaging member 13 is rendered inoperative by turning the lever 17., so that the block 19 is out of the way of the sash 11, and locking the rod 14L in position by means of the latches 25 and 27 It is evident that instead of attaching the latch to the lower sash it might equally well be secured to the upper sash so as to prevent movement thereof, or to any one of two adjacent members normally slidable relative to each other, and thus prevent relative movement in one direction.

In Fig. 7 a latch 28 is shown secured to a door 29 adjacent the floor 30 in such a way as to prevent swinging of the door 29 in one direction, when the latch is in operative position.

In 8 two latches 31 and 32 are secured at the top and bottom respectively of a barn door 33 shown as suspended from a track 34 in the well known manner. The latch 31 is adapted to engage the track 33 while the latch 32 engages the floor 35.
